SFM 6.1 Slurry Flow Meter
SENSOR MOUNTING LOCATION
The position of the sensor is one of the most important considerations for accurate slurry flow
measurement. The same location guidelines apply to slurry as most other types of flow meters.
Before permanently mounting a slurry sensor onsite testing is recommended to determine optimum
mounting position. Use the sensor coupling compound (supplied with each Greyline flow meter, or
petroleum gel, acoustic compound or electrocardiograph gel). Take several readings around the axis of
the pipe and then at several points upstream and downstream from the selected position, checking for
consistent readings. Avoid high or low reading areas. Mount the sensor where consistent (average)
readings were obtained or continue testing on another pipe section.
VERTICAL OR HORIZONTAL PIPE - Vertical pipe
runs generally provide evenly distributed flow. On
Horizontal pipes and liquids with high concentrations
of gas or solids, the sensor should be mounted on the
side (3 or 9 o’clock position) to avoid concentrations of
gas at the top of the pipe, or solids at the bottom. For
liquids with minimal gas bubbles (e.g. potable water)
the sensor should be mounted on the top of a horizontal
pipe (12 o’clock position) to obtain the best signal
strength.
VELOCITY INCREASING DEVICES: Generally the sensor must be mounted away from flow
disturbances such as valves, pumps, orifice plates, venturis or pipe inlets and discharges which tend to
increase flow velocity. Velocity increasing devices often cause cavitation, or rapid release of gas
bubbles, and readings both up and downstream may show much higher velocity. As a guideline, mount
the sensor at least 20 diameters upstream or 30 diameters downstream from velocity increasing devices.
Required distance from a velocity increasing device will vary in applications depending on the flow
velocity and the characteristics of the liquid itself.
TURBULENCE INCREASING DEVICES: Elbows,
flanged connections and tees tend to introduce
desirable conditions of an evenly distributed flow
profile with some air or gases entrained in the flow.
Sensor mounting 6 pipe diameters upstream and 10
diameters downstream from these disturbances is
generally optimum.
The sensor is designed to mount longitudinally on a straight section of pipe. Do not attempt to mount it
on bends, elbows or fittings.
Page 16
SFM 6.1 Slurry Flow Meter
SENSOR MOUNTING
Prepare an area 2" wide by 4" long (50mm x 100mm) for sensor bonding by removing loose paint, scale
and rust. The objective of site preparation is to eliminate any discontinuity between the sensor and the
pipe wall, which would prevent acoustical coupling.
A PC4 Sensor Mounting Kit is supplied with each Greyline flow meter. It includes recommended
coupling compound in a plastic applicator and a stainless steel mounting bracket with adjustable pipe
straps.
Page 17
SENSOR COUPLING
For permanent or temporary bonding, the following are recommended:
a) Dow Corning silicon compound #4 (supplied)
Additional supply: order Greyline Option CC
b) High Temperature compound
Additional supply: order Greyline Option AP-1W
c) Water-based sonic compound: Order Greyline Option CC30
d) Electrocardiograph gel
e) Petroleum gel (Vaseline)
The above are arranged in their order of preferred application.
d & e are only good for temporary bonding at room temperature.
DO NOT USE: Silicon RTV caulking compound (silicon rubber).
SFM 6.1 Slurry Flow Meter
Use the PC4 pipe clamp (supplied) as illustrated above or
use a loop of electrical tape for temporary mounting. Apply
silicon coupling compound #4 to the coloured face of the
sensor. A bead, similar to toothpaste on a toothbrush, is
ideal. Do not overtighten (crush the sensor).
The sensor must be fixed securely to the pipe with coupling material
between the sensor face and the pipe. Sensor installation with
excessive coupling compound can result in gaps or voids in the
coupling and cause errors or loss of signal. Insufficient coupling
compound will create similar conditions.
Over time temporary coupling compounds (e.g. Petroleum Gel) may gradually sag away from the sensor
resulting in reduced signal strength and finally complete loss of signal. Warm temperatures, moisture
and vibration will accelerate this process. Dow Corning Silicone Compound #4 as supplied with the
SFM 6.1 (and available from Greyline Instruments) is recommended for semi-permanent installations.

ENCLOSURE INSTALLATION
Locate the enclosure within 20 ft (6 m) of the sensor (500 ft -150 m optional). The enclosure can be wall
mounted with the four mounting screws (included).
Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to
overheating and condensate. In high humidity atmospheres, or where temperatures fall below freezing,
Option TH Enclosure Heater and Thermostat is recommended. Seal conduit entries to prevent moisture
from entering enclosure.
NEMA4X STAINLESS STEEL
Insert #14 screws (supplied) through the four enclosure mounting
holes to secure the enclosure to the wall or mounting stand.
Additional conduit holes can be cut in the bottom of the enclosure
when required. Use a carbide tipped hole cutter to cut the required
holes.
DO NOT make conduit/wiring entries into the top of the enclosure.
Note: Grounding must be provided as part of the installation. Ground
in accordance with the requirements of the National Electrical Code.
System grounding is provided by connecting grounding wires from
all conduit entries to the steel mounting plate or another point which
provides continuity.
CLEANING
Cleaning is not required as a part of normal maintenance.

SENSOR CABLE RESISTANCE TEST
Unplug the green sensor terminal from the slurry board and connect the sensor wires as shown. With a
multimeter, perform resistance checks for each set of wires. One single loose terminal may cause false
readings.
Test across shield and core of each wire: TMTR (black/white) and RCVR (black). Resistance should be
around 82.5K ohms for any cable length. High readings indicate an open circuit and low readings
indicate a short or partial short in the sensor cable.

COMMON QUESTIONS AND ANSWERS
The pipe vibrates. Will it affect the flow meter?
Common vibration frequencies are far lower than the sonic frequencies used by the Greyline flow meter,
and will not normally affect accuracy or performance. However, applications where very weak
ultrasonic signal is present (when sensitivity is adjusted to maximum and signal strength is low),
accuracy may be affected by pipe vibration, or the flow meter may show readings under no-flow
conditions. Attempt to relocate the sensor on a pipe section where vibration is reduced, or arrange pipe
mounting brackets to reduce vibration at the sensor mounting location.
The flow meter must be installed in a high noise environment. Will this affect operation?
Greyline flow meters are designed to discriminate between environmental noise and the ultrasonic
signal. High noise environments may affect the flow meter’s performance where low signal strength
and/or low flow velocities are being measured. Relocate the sensor in a more quiet environment if
possible.
Will pipe corrosion affect accuracy of the flow meter?
Yes. Rust, loose paint etc. must be removed from the outside of the pipe to provide a clean mounting
position when installing a slurry sensor. Severe corrosion/oxidation on the inside of the pipe may
prevent the ultrasonic signal from penetrating into the flow. If the pipe cannot be cleaned, a spool piece
(PVC recommended) should be installed for sensor mounting.
What effect do pipe liners have on the flow meter?
The air gap between loose insertion liners and the pipe wall prevent the ultrasonic signal from entering
the flow. Better results can be expected with bonded liners such as cement, epoxy or tar, however an on
site test is recommended to determine if the application is suitable for a slurry flow meter.
Why is Doppler ultrasonic only recommended for liquids containing suspended solids or gases?
The slurry sensor transmits sound into the flow stream which must be reflected back to the sensor to
indicate flow velocity. Gas bubbles or suspended solids act as reflectors for the ultrasonic signal. As a
guideline, Greyline slurry flow meters are recommended for liquids containing solids or bubbles with a
minimum size of 100 microns and a minimum concentration of 75 ppm. Most applications (except
potable, distilled or deionized water) will meet this minimum requirement.
Can the sensor be submerged in water?
Yes, for short periods of time or by accident, but it is not recommended for continuous operation. The
sensor is constructed to withstand submersion to 10 psi without damage, but external liquid moving in
contact with the sensor can be interpreted as flow and cause false readings.
What is the purpose of the Signal Strength Display?
Ultrasonic signals of very low strength are not accepted or processed by the instrument. This feature
assists in rejection of environmental noise and vibration. Use the display to evaluate signal strength in
your application. Strong signals will increase in percentage to a maximum of 100% or greater.
Page 25
SFM 6.1 Slurry Flow Meter
Can I change the length of the sensor cable?
Yes. Technological advances in Greyline ultrasonic design allow cable lengths up to 500 ft (152 m) with
no loss of signal strength. Extended cable (Greyline Option DXC) should be installed in rigid or flexible
conduit for mechanical protection. Use only Greyline shielded coaxial pair (RG174U) cable. Cable
junctions should be made through a terminal block and housed in a watertight metal junction box
(Greyline Option DJB). BNC coaxial connectors (TV cable type) are not recommended for cable splices.
Does the SFM 6.1 require periodic recalibration?
SFM 6.1 calibration does not drift over time. The solid state sensor has no moving parts to wear and
affect calibration. The ultrasonic flow technique generates an ultrasonic signal proportional to the
velocity of flow. All Greyline timing/counting circuits use crystal-controlled frequency references to
eliminate any drift in the processing circuitry.
ISO 9000 or similar quality management systems may require periodic and verifiable recalibration of
flow meters. SFM 6.1 Slurry Flow Meters may be returned to Greyline for factory calibration and issue
of a new NIST traceable certificate. Refer to the ‘Product Return Procedure’ section of this manual for
return instructions.
